Heat Stress: How is the Alarm jack on the side of the QT-15 used?

The alarm jack is connected to a relay. The normal condition of the relay (no for normally open or nc for normally closed) is set when the temperature alarm level is set. Then when the QT-15 goes into an alarm, the state of the relay will change. External devices connected to the QT-15 alarm jack are turned on or off when that relay changes conditions.
